Update output parser for NetMHCpan-4.1 and NetMHCIIpan-4.0

[arglog]

The current output parser for NetMHCpan4 is no longer compatible with the output of NetMHCpan-4.1.

Also similar for NetMHCIIpan. The current parser does not work well with the recently released NetMHCIIpan-4.0.

Ha, I think Morten Nielsen just likes to mess with us :-)

@julia326 @timodonnell -- anyone want to take this? If not, I will

I was actually planning on doing this this week, just talked to @timodonnell about it this morning :)

@julia326 i think you fixed this, and it can be closed?

I just put a comment in the above PR, I don't believe this is addressed in mainline (as suggested above). Any interest in resolving this still?
